A comparative study for two LiNbO3 cuts (Y-Z and Y-X) in detecting bulk acoustic microwaves using Probabilistic Neural Network

This work is mainly on the detection of the bulk acoustic waves (BAWs), where we have compared two Lithium Niobate cuts (Y-Z and Y-X), during the propagation of the acoustic microwaves in the piezoelectric LiNbO3-substrate. In this paper, we have used the classification by Probabilistic Neural Network (PNN) as a tool for numerical analysis in which we classify all the values of the real and imaginary parts of the attenuation coefficient for the propagation velocity. This analysis can allow us to demonstrate the best possibility in utilization for the BAW generation. This study will be very interesting in modeling and realization of acoustic wave devices (ultrasound) based on the propagation of acoustic microwaves. Keywords: Acoustics microwaves, Bulk waves, Piezoelectric material, Probabilistic Neural Network (PNN), The attenuation coefficient
